Overview

XC2361B40F80LAAHXUMA1 from Infineon Technologies is a 16/32-bit single-chip microcontroller in the XC2000 Family / Value Line, featuring an 80 MHz CPU clock (12.5 ns instruction cycle), 320 KB on-chip Flash, 16 KB PSRAM, and integrated MultiCAN Rev. 2.0B with 64 message objects across up to 3 CAN nodes. It supports automotive body control modules requiring real-time PWM generation, analog sensing, and CAN gateway functionality.

For engineers reviewing the XC2361B40F80LAAHXUMA1 datasheet, XC2361B40F80LAAHXUMA1 pinout, XC2361B40F80LAAHXUMA1 application, or XC2361B40F80LAAHXUMA1 equivalent, key selection criteria include its 100-pin LQFP package, 3.0–5.5 V single-supply operation, 16-channel CCU6x PWM units, dual 10-bit ADCs with sub-1 μs conversion, and on-chip Memory Protection Unit (MPU) for ASIL-B–capable firmware partitioning.

Technical Context

The XC2361B40F80LAAHXUMA1 implements a C166-compatible five-stage pipeline CPU with zero-cycle jumps, one-cycle 16×16 multiply, and background 32/16 division in 21 cycles. Its memory subsystem includes 8 KB SBRAM, 2 KB DPRAM, and ECC-protected Flash supporting error detection and correction.

Peripheral integration centers on deterministic real-time control: two synchronizable 10-bit ADCs (≤1 μs conversion), CCU6x units for complementary PWM with dead-time insertion, and a MultiCAN module with full CAN 2.0B compliance, 64 message objects, and hardware message filtering-enabling robust vehicle network gateways without external arbitration logic.

FAQ

What is the maximum operating temperature range for XC2361B40F80LAAHXUMA1?

The XC2361B40F80LAAHXUMA1 is qualified per AEC-Q100 Grade 2, supporting continuous operation from –40°C to +125°C ambient temperature. Junction temperature must remain below 150°C under worst-case power dissipation; thermal design requires ≥2 cm² copper pour on VDDP/VSSP layers and ≤20°C/W board-level thermal resistance.

Does this MCU support bootloader updates over CAN?

Yes-XC2361B40F80LAAHXUMA1 includes an on-chip bootstrap loader (BSL) that accepts firmware images via CAN using standardized UDS (ISO 14229) services. The BSL resides in protected ROM, supports signature verification, and operates independently of application code, enabling secure field updates without JTAG access.

Is the MultiCAN module compatible with CAN FD?

No-the MultiCAN module in XC2361B40F80LAAHXUMA1 implements CAN 2.0B only (up to 1 Mbps), not CAN FD. It supports full CAN and basic CAN modes, 64 message objects, and hardware filtering, but lacks the extended data length (up to 64 bytes) and bit-rate switching features of CAN FD.

What debug interfaces are supported?

XC2361B40F80LAAHXUMA1 supports On-Chip Debug Support (OCDS) via both JTAG and Infineon's Device Access Port (DAP). DAP enables faster trace streaming and real-time variable monitoring, while JTAG ensures broad toolchain compatibility with Lauterbach, iSYSTEM, and PLS UDE debuggers.
